I think that the answer is projector. It seems that none of them are "smart", they offer great quality and have a longer life. The downside is mounting them, but it's a one time job.
I was going to make that exact same comment. I bought a JVC video projector (B-stock for a steep discount) and it's great, amazing picture on a very large screen and no wifi, data collection or anything, it's dumb as a brick :) (well assuming a brick that can do hdr tone mapping, etc.. :))
